The rolling bearings produced by Longchangjie Machinery, as core components of precision machinery, achieve efficient anti-friction between the shaft and the shaft housing through a unique structural design. This bearing is mainly composed of an inner ring, an outer ring, rolling elements and a cage.The following are the specific functions of rolling bearings:

In daily engineering and life scenarios, we often use PP pipes and PVC pipes. The differences between these two types of pipes in practical applications are worth our in-depth understanding.

The PE pipes produced by Qingdao Longchangjie Machinery are themselves a type of plastic pipe, which is made of polyethylene (PE) resin. To compare which is more environmentally friendly, PE pipes or other plastic pipes, a comprehensive analysis of their materials, production and usage processes is required.

The PP pipes produced by Longchangjie Machinery Co., Ltd. are widely used in various fields, including the transportation of chemical media, chemical production and storage, as well as specific processes.
